This subclass of RSA is the default implementation
of the RSA algorithm and is a wrapper around the Windows Crypto API.

This class defines several new members in addition to those of the
RSA class; the Encrypt( ) and
Decrypt( ) methods encrypt and decrypt
System.Byte arrays with the RSA algorithm. The
SignHash( ) and VerifyHash( )
methods create and verify digital signatures for cryptographic hash
codes. The SignData( ) method creates a
cryptographic hash code for data read from a
System.IO.Stream or a
System.Byte array and creates a signature for the
result.

RSACryptoServiceProvider does not implement the
EncryptValue( ) and DecryptValue(
) methods defined in the RSA class.
